Red&Black thermal!
These labels are nice because the black and red don't seem to "blend" like most dual-color thermal printer labels. Like all NIIMBOTS labels, they're automatically detected by the printer and have a readout in the app for how many labels are left. Will buy again!

Nice Color, Red and Black Print (B21 PRONiimbot Printer Only!)
I have a Niimbot B 21 Pro and these little kraft labels ended up being perfect to label the bottles of homemade vanilla I gave out for Christmas. You can print in both red and black on these labels, but ONLY with the B21 Pro--not any other model of Niimbot printer. I love how the machine automatically lines up the roll in the printer so you are always perfectly aligned both horizontally and vertically. These are bigger than you might expect, so get out a ruler and make sure that your application calls for this particular size. The sticker material adheres very well, and the color of these labels gives a very rustic look. These are a great addition to my little collection of label rolls for the B21 Pro label printer.

Nice label size and love the color
Why did you pick this product vs others?: Color Label quality: Only one in a “color” to really differentiate between labels
